Android -- Dialog动画

window_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
        android:duration="500"
        android:fromXDelta="0"
        android:fromYDelta="1000"
        android:toXDelta="0"
        android:toYDelta="0" />
</set>

window_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
        android:duration="500"
        android:fromXDelta="0"
        android:fromYDelta="0"
        android:toXDelta="0"
        android:toYDelta="1000" />
</set>

将动画配置到style中

<style name="main_menu_animstyle">
       <item name="android:windowEnterAnimation">@anim/settingswindow_in_anim</item>
       <item name="android:windowExitAnimation">@anim/settingswindow_out_anim</item>
   </style>

将动画应用于Dialog

Window window = dialog.getWindow();
//设置显示动画
window.setWindowAnimations(R.style.main_menu_animstyle);
WindowManager.LayoutParams wl = window.getAttributes();
wl.x = 0;
wl.y = getWindowManager().getDefaultDisplay().getHeight();
//设置显示位置
dialog.onWindowAttributesChanged(wl);//设置点击外围解散
dialog.setCanceledOnTouchOutside(true);
dialog.show();
